The Rocky Mountain Audio Fest 2009, held last week in Denver, showcased the best and brightest in new high-end headphones and iPod sound enhancing gear.

I blogged about Wadia's super iPod dock, the 170i Transport last year, and Wadia now has a matching digital-to-analog converter/power amplifier, the 151. It has one USB, one Toslink, and two coax inputs. The 170i was the first "dock" to extract a digital output from an unmodified iPod, so for those who really care about sound quality, the Wadia 151 will be the way to go. The 151 PowerDAC will soon be available in black and silver.

Jack Wu of Woo Audio brought a nice selection of his tube headphone amplifiers to the show. I'm a huge fan of Woo Audio, its amps have made my Grado and Sennheiser headphones sound better than ever. Woo was also showing prototypes of its upcoming digital-to-analog converters, the sound showed great promise.

Tyll Hertsens, the headphone answer man.

Headroom's Tyll Hertsens is my headphone guru. He's a head case of the highest order, and Headroom is a great source for headphones and makes superb headphone amplifiers under the Headroom name. Hertsens is about to start a blog, and I'll be checking it regularly to learn more about what's going on in Hertsen's, er, head.

Virtue Audio's upcoming desktop amplifier.

Lastly, Virtue Audio's Seth Krinsky showed me this nifty little desktop unit, the upcoming dual-mono Virtue THREE amplifier. It will be good for more than 130 watts per channel. I can't wait to hear the finished design. Virtue offers a complete line of amplifiers and digital-to-analog converters. I will have a Virtue TWO amp very soon, I'll be using it with a pair of amazing Audioengine P4 speakers. Watch for the Audioengine review in this blog.

Not really. Pop it in, pipe it through your speakers, use the remote control to access the music...it couldn't be easier.
It sounds like you might have an aversion to really good digital sound.

No aversion to digital sound, would just prefer a smaller all-in-one unit.

what bitrate do most people use for music loaded to their iPods? if it's 320, then maybe....maybe...a Wadia rig wouldn't be a crazy purchase. but i don't know many people who load up their iPods with uncompressed files. and if it's mp3s, you ain't gettin' really good digital sound.

one_flat_monkey, I totally agrree with you. Whenever I see product like this hooked up to an ipod I think to myself "What an Oxymoron". I prefer uncompressed audio as most audiophiles do but I certainly don't have my ipod configured that way.

About The Audiophiliac

Ex movie theater projectionist Steve Guttenberg has more or less successfully hitched his future to home theater, but he still pines for the clickity-clack of 35 MM projectors and all the stale popcorn he could eat. Between projectionist gigs he worked as a high-end audio salesman for sixteen years, and produced records for an audiophile label. Oh, and one more thing, nothing annoys Steve more than being confused with the other Steve Guttenberg, the washed-up Police Academy actor.
